Fig. 6From: Evaluation of oral keratinocyte progenitor and T-lymphocite cells response during early healing after augmentation of keratinized gingiva with a 3D collagen matrix - a pilot studyOral mucosa and collagen matrix. Oral tissue samples before the procedure (a)(HE, x10), one week (b)(HE, x40) and 2 weeks after the procedure (c)(HE, x40). Histological assessment shows that 7 days following surgery, the oral epithelia is still forming, while at 14 days the architecture closely resembles the pristine gingiva (Scale bar - 100μm)Back to article page
